Description

A browser message processing method and device

technical field

The invention relates to the technical field of Windows message processing, in particular to a browser message processing method and device.

Background technique

The Windows operating system is a message (Message) driven system. Windows messages provide a means of communication between applications and between applications and the Windows operating system. The functions that applications want to achieve are triggered by messages and completed by responding to and processing messages.

All input devices of the computer are uniformly monitored by Windows. When an event occurs, Windows first puts the input message into the system message queue, and then copies the message to the corresponding thread message queue of the application. The message processing program of the application program will repeatedly detect the message queue, and after converting the detected messages, distribute them to the corresponding window functions, and the corresponding window functions will process the messages. This is the process that an event must go through from its occurrence to its arrival at the window function for processing.

However, in the Windows operating system, messages are not preemptive, that is, regardless of the priority of events, they are always processed in the order of arrival (except for some system messages), which may cause some adverse effects. For example, some real-time external events may not be processed in time, affecting the realization of specific functions of the application. For example, for a browser, the application is a web browsing tool that requires frequent interaction with the user. When the user triggers some external events, if they are not processed for a long time, some operations may be invalidated, and so on.

Therefore, a technical problem that urgently needs to be solved by those skilled in the art is how to process browser messages more flexibly so as to better realize browser functions.

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings required in the embodiments. Obviously, the accompanying drawings in the following description are only some of the present invention. Embodiments, for those of ordinary skill in the art, other drawings can also be obtained based on these drawings without any creative effort.

Fig. 1 is the flowchart of the method provided by the embodiment of the present invention;

Fig. 2 is a schematic diagram of a device provided by an embodiment of the present invention.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

Referring to Fig. 1, the embodiment of the present invention firstly provides a kind of browser message processing method, and this method can be applied in an application program (this application program can be a kind of application program developed for realizing this message processing function, also can be Adding the message processing function on the basis of the existing browser, etc.), during specific implementation, the method may include the following steps:

S101: The application program creates a message queue;

The message queue is created by the application program itself, so the application program can decide the order in which the messages are arranged, and can also adjust the order by itself.

S102: Take out all current messages from the message queue created by the operating system for the browser thread, and put them into the message queue created by the application program;

In order to better understand this step, the message processing process in the operating system is briefly introduced below. Generally speaking, a message (take an external input message as an example) will go through the following process from generation to final processing: (1) When the mouse or keyboard has an action, the device driver converts the input operation into a message and puts it into (2) Every time the operating system removes a message from the system message queue, it will judge which target window the message belongs to, and then distribute it to the message queue of the thread that created the target window. The window created for it by the message queue receives all mouse and keyboard messages; (3) the thread removes messages from its message queue and instructs the system to distribute these messages to the correct window to process the message. It can be seen that the operating system will create two message queues, one is the system message queue, and all messages will be put into this system message queue first; the other is the thread message queue, and all messages that need to be processed by a window created by a thread will be into the thread's message queue.

Correspondingly, for the browser program running in the operating system, the operating system will also create a message queue for the browser thread, and when the message taken out from the system message queue belongs to a certain thread of the browser, it will The message is put into the thread's message queue. The embodiment of the present invention is to take out the threads that have been distributed to the message queue of the browser thread, and store them in the message queue created by the application program itself.

It should be noted that the messages in the message queue of the browser thread may include system messages (that is, messages generated by the operating system) in addition to the above-mentioned externally input messages (that is, messages generated by the mouse and keyboard, etc.). ), in addition, it may also include messages generated by the browser itself. For example, an operation may not be processed immediately. At this time, the delayed processing can be performed by generating a message, that is, the message is first put in the message queue Queue to delay the processing time of the message; or some operations may need to be executed across threads. At this time, it can also be placed in the message queue first, and then distributed to the corresponding thread message queue, and so on. In the embodiment of the present invention, when the current message is taken out from the message queue of the browser thread, all the above-mentioned types of messages can be included, that is, all messages, no matter they come from external input, the operating system or the browser itself, can be It is taken out and put into the message queue created by the application program itself, so as to adjust the order of the messages. Of course, the execution order of some system messages may not allow adjustment, and at this time, the order adjustment of such system messages may not be performed.

In addition, it should be noted that when the message is retrieved from the message queue of the browser thread, an API (Application Programming Interface, application programming interface) function provided by the operating system can be used to perform the process. For example, the following API function can be used directly: PeekMessage.

Of course, in order to avoid errors during the running of the program, after the current message is fetched from the message queue created by the operating system, the fetched message can also be cleared from the message queue created by the operating system.

S103: Judging whether there is a message meeting the preset condition among the fetched messages, and if so, adjusting the order of the messages meeting the preset condition;

The specific basis for adjusting the message can be determined according to the needs of the actual application. For example, it can be considered that some messages generated by operations related to user interaction need to be processed first. At this time, such messages can be put into the message The higher position in the queue. For another example, if the user is watching a video, video-related operations may need to be prioritized. At this time, the message corresponding to this operation can be put into a relatively front position in the message queue. For another example, if the user performs other operations while watching a video, it can be considered that the message corresponding to the user's operation needs to be queued, processed in advance, and so on. In addition, it can also be judged whether each message needs to be processed by the window currently in focus, and if so, the order of the message can be advanced. Furthermore, some messages (especially messages generated by the browser itself) may need to be executed before another message. At this time, the message can also be adjusted before the other message, and so on.

It should be noted that the operating system will number each message, and each message has its own ID. The message can include information such as window handle and message type, which can be obtained through the API functions of the system (for example, through GetInputState, you can Check whether there is a keyboard or mouse message in the thread message queue, you can check a certain type of message in the message queue through GetQueueStatus, etc.) According to this information, you can know which window each message needs to be processed and the corresponding operation of the message, etc. etc., and then the order of each message in the message queue can be determined according to the preset rules. For example, it is found that the operation corresponding to a certain message needs to be processed by a certain video playback window, and the priority of this type of message is preset to be relatively high, so the message can be placed at a relatively high position in the message queue. Maybe even in the first place, etc.

S104: According to the sequence of the messages in the message queue created by the application program, distribute each message to a corresponding window of the browser for processing.

Since each message has been re-adjusted in the message queue created by the application program, each message can be distributed and processed according to the adjusted order. Specifically, since the message is taken out from the message queue of the browser thread in step S102, the message can be directly distributed to the corresponding browser window during distribution processing, and the corresponding window can process the message. That is to say, it is equivalent to that after the operating system distributes the messages in the system queue to specific browser thread message queues, it is not the thread itself that distributes the messages to the specific windows, but the message queue described in the embodiments of the present invention. The application program of the message processing function completes the distribution work instead of each specific thread. During specific implementation, when the operation of distributing messages is completed instead of a specific thread, it can also be implemented by the application program with message processing function using the API function provided by the operating system (the API function can be: DispatchMessage).

In short, through the message processing method provided by the embodiment of the present invention, since the application program can create a message queue by itself, and take out the current message in the message queue created by the operating system for the browser thread, and put it into the self-created message queue, Therefore, the execution order of the messages can be adjusted, instead of following the first-come-first-processed principle specified in the operating system, so that the messages in the message queue can be processed more flexibly. For example, some real-time external events can be processed in time, and if some messages that arrive later must be processed before other messages that arrive earlier to achieve the intended effect, the messages that arrive later can be processed in advance. Before the message that arrives earlier, so as to achieve the intended effect.

Corresponding to the browser message processing method provided in the embodiment of the present invention, the embodiment of the present invention also provides a browser message processing device. Similarly, the device is applied to an application program, as shown in FIG. 2, and the device includes the following units :

A queue creation unit 201, used for an application to create a message queue;

The message distribution unit 204 is configured to distribute each message to a corresponding window of the browser for processing according to the order of the messages in the message queue created by the application program.

Of course, in order to avoid errors during the running of the program, after the current message is fetched from the message queue created by the operating system, the fetched message can also be cleared from the message queue created by the operating system. During specific implementation, the device may also include:

The clearing unit is configured to, after taking out all current messages from the message queue created by the operating system for the browser thread, clear the taken out messages from the message queue created by the operating system.

Wherein, during specific implementation, the sequence adjustment unit 203 may specifically include:

The first adjusting subunit is configured to judge whether there is a message that needs to be processed by the window currently in focus among the fetched messages, and if so, adjust the message to the front end of the message queue.

Alternatively, the order adjusting unit 203 may specifically include:

The second adjustment subunit is configured to judge whether there is a message related to user interaction among the retrieved messages, and if there is, adjust the message to the front end of the message queue.

Furthermore, the sequence adjustment unit 203 may specifically include:

The third adjusting subunit is configured to judge whether there is a second message that needs to be processed before the first message among the fetched messages, and if so, adjust the second message before the first message.

Through the message processing device provided by the embodiment of the present invention, since the application program can create a message queue by itself, and take out the current message in the message queue created by the operating system for the browser thread, and put it into the self-created message queue, so that The execution sequence of messages can be adjusted, instead of following the first-come-first-handled principle stipulated in the operating system, so that the messages in the message queue can be processed more flexibly. For example, some real-time external events can be processed in time, and if some messages that arrive later must be processed before other messages that arrive earlier to achieve the intended effect, the messages that arrive later can be processed in advance. Before the message that arrives earlier, so as to achieve the intended effect.
